            Bug ID: 110117
           Summary: Waking from Suspend causes screen to appear with grey
                    static (like a TV with no signal)
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

journalctl -b -1 -k

I am running Ubuntu 18.10. This is the PH517-61 Acer Predator Helios 500 with
the Ryzen processor. I have temporarily disabled suspend. If I do let the
laptop suspend and then hit the keyboard I get what appears to be a TV with no
signal. At this point I manually power down and then power up again and am able
to view things on screen.

I have reported this downstream here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813820

in log.txt I have attached the output of 'journalctl -b -1 -k'

uname -a: 5.0.2-050002-generic #201903131832 SMP Wed Mar 13 22:35:19 UTC 2019
x86_64 x86_64 x86_64 GNU/Linux

Loaded newer kernel from this source:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.0.2/

This is a Vega 56 card but here is what I get with this command:
lspci -k | grep -EA3 'VGA|3D|Display'
08:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Vega
10 XT [Radeon RX Vega 64] (rev c7)
        Subsystem: Acer Incorporated [ALI] Vega 10 XT [Radeon RX Vega 64]
        Kernel driver in use: amdgpu
        Kernel modules: amdgpu

glxinfo | grep "OpenGL version"
OpenGL version string: 4.4 (Compatibility Profile) Mesa 18.2.2



Expected Behaviour:
I expect to continue to be able to use my machine normally and be able to see
what is happening on screen.

Actual Behaviour:
Static on screen obscures everything.

I don't see anything immediately wrong in the log at the first glance at least
so it'd be helpful if you could post your dmesg log from after the problem
occurred with drm.debug=4 in your kernel boot parameters.

Please post your xorg log if applicable as well.

Steps I took:
1. added drm.debug=4 to /etc/default/grub
2. sudo update-grub
3. reboot
4. reproduced the issue
5. rebooted using ctrl-sysrq-reisub
6. dumped this dmesg into log.txt

I would like to add to this some additional troubleshooting I have performed,
in case it is of use.



just a short history: I am unable to suspend with any Linux distribution and be
able to resume again. Currently running Ubuntu 19.04.

I am attempting to follow the steps here to trace the problem:
https://wiki.ubuntu.com/DebuggingKernelSuspend

This is what I have done so far:

$ sudo apt install pm-utils
$ sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend"

I resumed but got my usual screen garbage (looks like static on the screen). I
ssh'd in and did a sudo reboot

Right away I ran this:

$ dmesg > dmesg_post_boot.txt

I looked for Magic number in the dmesg per the ubuntu wiki above and found
these lines:

[    0.950964]   Magic number: 0:66:1001
[    0.950965]   hash matches drivers/base/power/main.c:1012

Now the instructions are to exclude this module from the next boot and see if I
can replicate the problem. How do I exclude main.c or do I even want to? Is it
even possible that the bug is here?

I can confirm this behavior at Ubuntu 18.04.2 LTS with Acer PH517-61 notebook.

The minor addition is that the issue concerns only the built-in display. In two
display configuration after wake up the external display seems to be normal.

happened to me too using Opensuse Tumbleweed with kernel 5.1.7 and MESA 19.0.5,
I have been try to disable power management in amdgpu via kernel paramater but
still happen.
this happen to me while I play some game(s) such Mutant Zero Year and Uboat on
the STEAM, while other games seems doesnt trigger this static greyed display
such as The Witcher 3
I cant log/reproduce any error messages since I'm using the laptop display
(Acer Predator Helios 500 Ryzen 2700 with vega56)
but maybe I can show my recorded video taken from my phone while this display
glitch happened.

This issue also occurs on Windows. AMD support says that it will be fixed in
the next Windows update; could they possibly contribute that same fix to Linux?
